Question Help
The pressure of a gas in a container varies directly with its temperature and inversely with its volume. At a temperature of 90 Kelvin and a volume of 10 cubic meters, the pressure is 37.8 newtons per square meter. What is the pressure if the temperature is increased to 100 Kelvin and the volume is decreased to 6 cubic meters?

Answer 1

Surely the course textbook and instructor will have covered this!

The formula's word form tells everyone that P = k•T/V.

 

The second sentence gives you values for P, T and V, enabling you to determine k.

 

The third sentence(the question) can now be handled because you know k and are given new T and V.
